Hello,
In specs of this server, it saz esx embedded. Do I have to install esx? Read something about a flash disk that esx can be booted from? Anybody using this embedded feature?
I also need a 4 port network card that is both supported by server and esx 3.5. Any suggestion is appreciated.

Thanks

When you select the option for ESXi Embedded you'll get a flash device added to the host which will have ESXi pre-installed. If you're selecting the ESXi 3.5 or 4.0 option you'll note that IBM list a USB memory key.

The Intel or Broadcom NIC that you can get from IBM should be fine, but I would double check the HCL if you plan to use ESXi 3.5.
